Title: Substance with lipo-oligosaccharide structure capable of acting as plant-specific symbiotic signals, process for producing them and their applications
Inventor: LEROUGE PATRICE
IPC: A01N63/00
Filed: 1991-04-05
Abstract: An essentially pure substance has a structure of a Nod factor or one of its analogues. The Nod factor is characterized by the fact that its biosynthesis is controlled by at least one nodulation gene ($i(nodA,B,C)) common to the Rhizobiaceae, in particular to the genera $i(Rhezobium), $i(Bradyrhizobium), $i(Sinorhizobium) and $i(Azorhizobium). This substance consists of a lipo-oligosaccharide which is not a derivative of the exopolysaccharides and which has the general formula (I). In formula (I), the Nod factor of which it has the strucutre is a plant-specific symbiotic signal and is capable of enhancing the capacity of the bacteria to infect the host plant with which it is associated and/or of accelerating the formation of nodules on the host plant with which it is associated and/or of inducing the transcription of symbiotic genes of the Leguminoseae. Applications to the treatment of plants and as an active therapeutic agent in humans and animals. G stands for a hexosamine variously substituted, for example by an acetyl group on the nitrogen, a sulphate group, an acetyl group and/or an ether group on oxygen R1?, R2?, R3?, R5?, R6?, R7?, which may be identical or different, stand for H, CH3?CO-, CX?HY?CO- where X is a whole number between 0 and 17 and Y is a whole number between 1 and 35, or any other acyl group, for example a carbamyl groupe, R4? stands for a saturated or mono-, di, or tri-unsaturated aliphatic chain containing at least 12 carbon atoms and n is a whole number between 1 and 4.

Patent CA-2084765-A1 (CA)
Inventor: SWANN LINSEY J
IPC: A62B19/02
Filed: 1992-06-05
Abstract: The breathing system comprises a canister (12) carrying layered filter-ing material, including activated carbon granules, a desiccant, a catalyst for the catalyzation of carbon monoxide to carbon dioxide, and electrostatically charged filters between the layers of filtering material. A mouthpiece (28) carrying a noseclip (33) and inhalation and exhalation check-valves and a whistle is disposed within a flexible, substantially completely transparent hear-through hood (34), both the mouthpiece (28) and hood (34) being dis-posed in the canister (12) between the filtering material and a cover for the canister. In use, the cover is removed, air inlet apertures are uncovered, and the hood (34) is drawn about an individual's head and substantially sealed about the neck. With the mouthpiece (28) in the individual's mouth, and no-seclip (33) closing off the user's nose, inhalation causes air to flow through the filtering material and the inhalation check valve and past the exhalation check valves. When exhaling, the exhalation check valves open to permit ex-haled air to flow into the hood. The inhalation valve closes during exhala-tion to prevent backflow of air through the filtering material. By exhaling in-to the hood (34), a slight positive pressure within the hood is established to prevent noxious gases, smoke particles and the like from entering the hood (34) through the neck opening (44).

IPC: B09B1/00
Filed: 1993-05-13
Abstract: An improved method and apparatus for waterproofing soil utilizing a flexible plastic sheet for providing a water barrier provides a system for readily detecting the presence of holes in the plastic material. The sheet includes a plastic layer which may be rendered electrically conductive by embedding conductive particles within it. The integrity of the sheet may then be monitored by establishing an electric field across the sheet and monitoring for sparks between the conductive plastic layer and a probe. Reliable and economical testing is possible, even in situations where electric leak testing was not previously feasible.
Patent CA-2096449-A1 (CA)
Title: Servo system
Inventor: NELSON ALFRED
IPC: G11B15/00
Filed: 1993-05-18
Abstract: SERVO SYSTEM                  Abstract of the Disclosure A master tape movable in a closed loop including a pinch roller transfers a mirror image to a slave tape movable in a closed loop including a capstan.  A thermomagnetic layer on the slave tape has a Curie temperature above which magnetic information is destroyed and below which magnetic information can be recorded on such layer.  The thermomagnetic layer is heated above the Curie temperature and is accordingly lengthened by thermal expansion just before the slave tape reaches the capstan.  A first guide contiguous to the heater regulates the slave tape tension.  A downstream portion of a peripheral surface, preferably defining a cylindrical segment, on the guide receives a pressurized fluid for sensing the tape tension in accordance with the tape width, distance from the cylinder axis, and the fluid pressure.  An upstream portion of the peripheral surface receives a vacuum adjustable to vary the spacing between the slave tape and the downstream portion.          This regulates the tape tension.  The master tape is lengthened by a second guide having the same construction as the first guide to compensate for the lengthening of the slave tape by the heater and the first guide, thereby producing a true mirror image on the slave tape after the slave tape has cooled to the ambient temperature.  Each of the master tape and the slave tape has a particular product of the Youngs modulus, tape width and tape thickness to provide a controlled strain on the tape when the tension on the tape is regulated.
Patent CA-2098126-A1 (CA)
Inventor: WU HSIEN-JUNG
IPC: B43K8/06
Filed: 1993-06-10
Abstract: ABSTRACT OF THE INVENTION          In spite of the upgrading of the production standard of arts and advertising work, a pen used for marking can only draw out a monocolor.  As a remedy, in the present invention the interior end of a marking pen is fabri-cated in such a way that a twin-inserted head or more is inserted separately into different colored ink tube, so that when the ink flows from the ink tube to the head of the pen, the color will mix naturally in the area ad-jacent to the middle of the bottom end on the head of the pen, so as to produce a gradually-layered color effect to further create multi-color changes to the advertizing work produced without going through a color spray finishing process.  The penholder is made of elas-tic material.  By pressing one's fingers against the penholder the ink contained therein will rapidly flow to the head of the pen, and further pass the two through holes on two connic bodies set on the top end of the head of the pen to make direct access to the bottom end until reaching the two ends of the head of the pen, to ultimately enhance the various color at the two ends and rapidly recover the gradually-layered color effect.

Title: Quantitative detection of nucleic acid amplification products
Inventor: CROSS LISA
IPC: C12Q1/6818
Filed: 1992-06-05
Abstract: A method of amplifying and quantitating a specific nucleic acid sequence in a sample using at least one oligonucleotide primer, a supply of nucleotides and optionally a probe complementary to part of the sequence, one of these including a radionuclide. In the presence of a polymerase the reagents form an amplified product based on the specific nucleic acid sequence. The amplified sequence is allowed to bind to a solid material comprising a fluorescer which fluoresces in proximity to the radionuclide and fluorescence is observed as a measure of the specific nucleic acid sequence.  The method can be applied to a range of well-known nucleic acid amplification techniques such as the Polymerase Chain Reaction. A  variation on the above method allows use of the Ligase Chain Reaction technique.
